BLOB Link (after fire I see source of blob)

Question

Hi
I have problem with link to uploaded file.
I created own table with BLOB column ("PLIK"), MIMETYPE, FILENAME, LAST_UPDATE_DATE.
I created PLSQL procedure which move blob from apex_application_files to my table (insert as select).
I created apex normal report on my table with Blob format mask and when I click on Download link I can see only web page with source of blob something like:
"%PDF-1.3 %�쏢 5 0 obj <> stream x��Vmo�6�D��\A�0�gժ�qJ��D�KI�$}��X����a�@���(�i�d��ٰA�y�..."
Can You help me ??

Andy,
There is a section in the manual about creating uploading and downloading files, you would need to create a procedure like this, and then grant execute to public
CREATE OR REPLACE PROCEDURE download_my_file(p_file in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM oehr_file_subject
WHERE id = p_file;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end download_my_file;
hope that helps,
